    • Ab initio study: Investigating the adsorption behaviors of polarized greenhouse gas molecules on pillar[5]arenes 

      Rauls, Eva; Ho, Quoc Duy (Peer reviewed; Journal article, 2023)
      Supramolecular organic frameworks (SOFs) based on Pillar[5]arenes (P[5]A) have shown great potential in capturing and separating greenhouse gases. In this study, we investigate the adsorption behaviors of other environmentally ...

    • Analytic structure of nonhydrodynamic modes in kinetic theory 

      Kurkela, Aleksi; Wiedemann, Urs Achim (Peer reviewed; Journal article, 2019-09)
      How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales ...

      Brauner, Tomas; Kadam, Saurabh (Journal article; Peer reviewed, 2017-11)
      The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ...

    • Bayesian inference of real-time dynamics from lattice QCD 

      Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2022)
      The computation of dynamical properties of nuclear matter, ranging from parton distribution functions of nucleons and nuclei to transport properties in the quark-gluon plasma, constitutes a central goal of modern theoretical ...

      Gorda, Tyler; Komoltsev, Oleg; Kurkela, Eero Aleksi; Mazeliauskas, Aleksas (Peer reviewed; Journal article, 2023)
      The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities. The constraining power of the QCD input ...

      Alvestad, Daniel; Fomin, Nikolai; Kersten, Jörn; Mæland, Steffen; Strumke, Inga (Peer reviewed; Journal article, 2023)
      We investigate enhancing the sensitivity of new physics searches at the LHC by machine learning in the case of background dominance and a high degree of overlap between the observables for signal and background. We use two ...

      Boguslavski, Kirill; Kurkela, Eero Aleksi; Lappi, Tuomas; Peuron, Jarkko (Peer reviewed; Journal article, 2021-05)
      Motivated by the initial stages of high-energy heavy-ion collisions, we study excitations of far-from-equilibrium 2+1 dimensional gauge theories using classical-statistical lattice simulations. We evolve field perturbations ...

    • Can cancer cells inform us about the tumor microenvironment? 

      Nævdal, Geir; Evje, Steinar (Peer reviewed; Journal article, 2023)
      Characteristics of the tumor microenvironment (TME) such as the leaky intratumoral vascular network and the density and composition of the desmoplastic extracellular matrix (ECM) contain essential information that determine ...

      Gorda, Tyler; Kurkela, Eero Aleksi; Paatelainen, Risto; Säppi, Saga; Vuorinen, Aleksi (Peer reviewed; Journal article, 2021)
      High-order perturbative calculations for thermodynamic quantities in QCD are complicated by the physics of dynamical screening that affects the soft, long-wavelength modes of the system. Here, we provide details for the ...

    • Collective flow in single-hit QCD kinetic theory 

      Kurkela, Eero Aleksi; Mazeliauskas, Aleksas; Törnkvist, Robin (Peer reviewed; Journal article, 2021-11)
      Motivated by recent interest in collectivity in small systems, we calculate the harmonic flow response to initial geometry deformations within weakly coupled QCD kinetic theory using the first correction to the free-streaming ...

    • Collider phenomenology of a unified leptoquark model 

      Faber, T.; Liu, Y.; Porod, W.; Hudec, M.; Malinsky, M.; Staub, F.; Kolesova, Helena (Peer reviewed; Journal article, 2020-05)
      We demonstrate that in a recently proposed unified leptoquark model based on the gauge group SU(4)C×SU(2)L×U(1) R significant deviations from the Standard Model values of R K and R K ∗ can be accommodated without any need ...

    • Comment on ''Szekeres universes with homogeneous scalar fields'' 

      Delgado Gaspar, Ismael; Sussman, Roberto A.; McNutt, David Duncan; Coley, Alan (Peer reviewed; Journal article, 2021-04)
      In two recently published articles, Barrow and Paliathanasis (2018, 2019) [1, 2] claim to have found exact solutions of Einstein’s field equations belonging to the class of non-trivial (i.e., spatially inhomogeneous) ...

    • Competition of chiral soliton lattice and Abrikosov vortex lattice in QCD with isospin chemical potential 

      Grønli, Martin Spillum; Brauner, Tomas (Peer reviewed; Journal article, 2022-04)
      We investigate the thermodynamics of two-flavor quark matter in presence of nonzero isospin chemical potential and external magnetic field. It is known that at sufficiently high isospin chemical potential, charged pions ...

      Dong, Lihua; Guo, Yun; Islam, Ajaharul; Rothkopf, Alexander Karl; Strickland, Michael (Peer reviewed; Journal article, 2022)
      We generalize a complex heavy-quark potential model from an isotropic QCD plasma to an anisotropic one by replacing the Debye mass mD with an anisotropic screening mass depending on the quark pair alignment with respect ...

      Mandal, Ipsita; Yao, Jia; Mueller, Erich J. (Peer reviewed; Journal article, 2021-03)
      Experiments on graphene bilayers, where the top layer is rotated with respect to the one below, have displayed insulating behavior when the moiré bands are partially filled. We calculate the charge distributions in these ...

      Albaladejo, M.; Nieves, J.; Tolos Rigueiro, Laura (Peer reviewed; Journal article, 2021-09)
      We study the behavior of the χc1(3872), also known as X(3872), in dense nuclear matter. We begin from a picture in vacuum of the X(3872) as a purely molecular (DD¯¯¯∗-c.c) state, generated as a bound state from a heavy-quark ...
